Reduction Mechanism Redox Reactions Lesson Summary Frequently Asked Questions What is reduction in chemistry? Reduction, any of a class of chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased. The electrons taken up by the substance reduced...
The copper ion undergoes reduction by gaining electrons to form copper. The magnesium undergoes oxidation by losing electrons to form the 2+ cation. Or, you can view it as magnesium reducing the copper(II) ions by donating electrons. Magnesium acts as a reducing agent. In the meantime, the ...
